Reflection (pheesics)

Reflection is the chynge in direction o a wavefront at an interface atween twa different
media sae that the wavefront returns intae the medium frae which it originatit. Common examples include the reflection o licht, soond an watter waves. The law o reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection.
